To (all whom it non/y concern.-

Be it known that we, JOHN FRANCIS PEASE and EBERIIARD SCHUMACHER,subjects of the King of Great Britain and Ireland, residing atDarlington, in the county of Durham,

England, have invented certain new and useful Improvements in Wheels forMotor-Cars, Cycles, or other Vehicles for Road or Rail; and we do herebydeclare the following to be 1 o a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to wheels as adapted i5 to motor-cars, cycles,and other vehicles,

either for road or rail, the object in view being to produce such wheelsof great strength and light weight at a low cost of manufacture.

The wheel is constructed in two main or principal sections, the plane ofdivision between which being the central plane of the wheels rotation.These main sections are preferably equal and similar, each having itsown hub abutting against the hub of the 2 5 other and both mounted onthe same bush, the two sections formed by stamping being clenchedtogether at their peripheries to form a complete wheel.

Having thus indicated the nature and util- 0 ity of our invention inorder that it may be clearly understood and readily carried into effect,we will proceed to further describe the same and for that purpose shallrefer to the accompanying drawings, in which a conven- 3, 5 ient form ofconstruction for the purposes of our invention is shown in Figures 1 and2,

Fig. 1 being a front elevation of the wheel and Fig. 2 a transversesectional view taken on line 00 :0 of Fig. 1.-

In the drawings, and more especially in Fig. 2, it will be observed thatthe two sections making up the wheel are preferably equal and similar,each having its own hub abutting against the hub of the other and bothmounted on the same bush 0. Each hub is made up of two apertured centerplates 0 a and b b, dished or hollowed out for strength and to provide amore extended bearing-surface on the bush 0. In some cases the innerhub-plate a or b terminates at the line or ring of contact with theouter hub-pl ate (1' or b, internally trussing the hollow hubtransversely thereof and particularly at the point of joindcr with thespokes, thereby preventing buckling at this point. Each of the outerhub-plates a 1) extends in the form of spokes d to its own periphery,which forms one side of the rim or tire e of the wheel, the finished orcombined shape of hub, rim, and spokes tak. 11g a form convenient forstamping out of a disk. When the two hubs are mounted in position on thebush c,'their peripheries are in contact and being of suitable form forthe purpose are made to constitute the tire-rim e by clenching or otherequivalent method of securing them to ether, the overlaps ealternatingwith each ot ier on either side of the wheel. The spokes d, which springfrom the hubs in two corresponding sets, converge toward each other inpairs, thus affording great mutual support combined with greatlightness, the spokes being hollowed out or moldedto any suitablesection conducing to this, or where still greater strength is requiredinstead of the inner hub-plate aor b terminating at the line or rin ofcontact with the outer hubplate a or both plates may extend in the formof spokes termin atingin aunited periphery, the spokes and peripherybeing ada ted for manufacture by stamping and clenc ing together, thetwo combination peripheries thus formed being clenched together toconstitute one tire. or rim, as before.

The bush 0 is preferably hexagonal in form to fit hexagonal openings inthe hubs or bosses of the wheel, the internal hub-plates a and I) havinglarger openings and the bush being correspondingly enlarged at thecenter 0 to fit them. Nuts f on the end of the bush afford convenientmeans for securing the hubs tight to ether. If a further interlockbetween the p ates of each hub is desirable to prevent any tendency forindependent rotation of either without the other, this can be-9 5conveniently effected by providing projections on the one to fit intocorresponding recesses of the other.

Having thus described the nature, object, and essential features of ourinvention and the manner of carrying the same into effect, we wish it tobe understood that the method or principle of building up a wheel ontwin hubs mounted on the same axle is not new, twin hubs set apart bysome suitable device having been described inthe specifications ofvarious Letters Patent from time to time and prior to the date of ourpresent application for Letters Patent. We therefore make no claim tothe use of twin hubs otherwise than when abutting together in the mannerembodied in and earned into practice by our improvements as abovespecified.

Having thus described our invention,what

we desire to claim and secure by Letters Patent of the United Statesis 1. A metallic wheel formed from two circular sections centrallyspaced apart and joined at their peripheries, and means internallytrussing the central spaced portion thereof comprising trussing memberscentrally abutting and diverging into engagement withsaid circularsection, substantially as described.

2. A metallic wheel formed from twocircular sections centrally spacedapart and joined at their peripheries, and means internally trussing thecentral spaced portion thereof, comprising trusslng-plates centrallyabutting and diverging outwardly and engagin said circular sections,substantially as described.

3. A metallic wheel formed from two cgrcular sections having comlementary center plates and peripheral p ates, said center plates beingspaced apart and the peripheral plates joined to ether to form thefelly, in combination witii trussing-plates, within said spaced portion,abutting centrally and projecting outwardly into engagement with saidsections,-forming with said center plates an internal truss for the .hubof the wheel, substantially as described. 1

4. A metallic wheel formed from two circuform the felly,

lar sections having complementary center plates and peripheral plates,said center plates being disk-shaped and s aced apart and the peripheralplates joined together to in combination with trussingplates, withinsaid spaced portion, abutting centrally and projecting outwardly intoengagement with said sections, formin with said center plates aninternal truss or the hub of the wheel, substantially as described.

5. A metallic wheel made from two disks each stamped out to form anapertured central plate, with spokes radiating therefrom and terminatingin an annular rim, said central plates being spaced apart and saidannular rims being joined and formed into the wheel-felly, incombination with apertured abutting plates located between said spacedcentral plates and diverging outwardly at their outer edges intoengagement with said central plates substantially at the place ofjoinder between said plates and spokes, and an axis member passingtransversely through said apertured plates, with meansfor forcing sametoward each other and holding same locked on said axis member,substantially as described.

'In testimony whereof we aflix our signatures in presence of twowitnesses.
